<div class="tree_txt_unlinked"><p>The
taxonomic superfamily Ceboidea has been thrown into flux recently
thanks to new molecular studies that have redistributed the taxa within
three taxonomic families: Cebidae, Pitheciidae, and Atelidae. All
ceboids are found only in the New World, probably arriving from Africa
sometime during or after the Oligocene. Species vary considerably in
diet, habitat, body size, and behavior, including the only nocturnal
platyrrhine <em>Aotus</em>.</p>
